Definitions

• the invention relates to an installation for fighting fire, for a unit provided with a hydraulic system, such as a ship.
• the object of the present invention is to provide a new installation for fighting fire which is improved over known installations for such units which have a hydraulic system.
• the installation according to the invention is mainly characterized in that the hydraulic system is arranged to be driven with water as drive medium, and that sprinklers or spray heads intended for fighting fire are connected to the power source of the hydraulic system.
• the concept water here of course includes certain additives, e.g. anti-corrosion additives.
• the power source of the hydraulic system is usually a hyraulic pump having a high operating pressure and a high volume capacity.
• the pump is in turn usually driven by a main power source, such as an electric generator.
• At least a part of sprinklers or spray heads intended for fighting fire are connected to the power source of the hydraulic system via the pressure line of the hydraulic system.
• Some sprinklers or spray heads can in addition be connected to the return line of the hydraulic system, in which case it, when activating the sprinklers or spray heads, is reason to close the return line after the last sprinkler or spray head, in order to maintain a sufficient pressure in the return line.
• the separate fire fighting hydraulics can be utilized for performing certain additional functions essential when a fire has started, such as closing fire doors, driving elevators etc.
• the regular main power source usually an electric generator
• an emergency generator often having less power than the regular generator, is capable of providing sufficient power for fighting the fire and for performing at least a limited number of additional important functions; the regular hydraulic system can then possibly be disconnected altogether.
• the inventive idea can widely be said to be that the same system is utilized both for fire fighting and for more or less regular hydraulic functions.
• Hydraulic systems in ships and the like generally have a high operating pressure, 100 bar or more. It is recommendable to use such sprinklers or spray heads which are presented e.g. in the international patent applications PCT/FI92/00060 and
• PCT/FI92/00155 are capable of operating at a high pressure, provide effective fire extinguishing with small amounts of water and can be made to produce concentrated fog-like sprays having a good penetration power.
• the installation for fighting fire can be utilized for spraying a fog of water droplets, having a typical diameter size of 30 to 150 microns, into the oil tanks for fire extinguishing and cooling, respectively.
